QUIZ: ELECTROMAGNETISM (NOTES 6.4-6.6)Answer Key1.A single circular loop of wire in the plane of the page is perpendicular to a uniformmagnetic field B directed out of the page, as shown. If the magnitude of the magneticfield is decreasing, then the induced current in the wire is ____We need to apply Lenz’s Law which states that an induced electric current flows in adirection such that the current opposes the change that induced it.Direction of Magnetic Field? Out of the pageIs the Flux Increasing or Decreasing? DecreasingDirection of Induced Magnetic Field? Out of the pageDirection of Induced Current? Counter-clockwise2.A 25 cm radius single circular wire coil is removed from a 4.5 x 10-4T magnetic field in 0.25 s. What is the EMF inducedin the coil?2
